Hello, I'm trying to build my kotlin package with gradle. I've setup the build.gradle as follows
Copy code
buildscript {
    ext.kotlin_version = '1.2.21'

    repositories {
	    jcenter()
    	mavenCentral()
    }

    dependencies {
	classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
	classpath "org.jetbrains.kotlin:kotlin-stdlib"
    }
}

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.2.21"
}

sourceSets {
    main.kotlin.srcDirs += "./"
}
I'm getting errors related to 
kotlin-stdlib
like

@Ishan Khare Is this the whole build.gradle?
if yes, you need to move the dependency of 
kotlin-stdlib
out of the 
buildscript
-scope
i
yes this is the whole build.gradle
after that change i get the following error
Copy code
FAILURE: Build failed with an exception.             

* Where:                  
Build file '/home/ishan/code/kotlin-server/server/build.gradle' line: 19                                  

* What went wrong:        
A problem occurred evaluating root project 'server'. 
> Could not find method classpath() for arguments [org.jetbrains.kotlin:kotlin-stdlib] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.
a
change 
classpath
to 
compile
, because you require the stdlib to be present during compilation
i
This is the update build.gradle
Copy code
buildscript {
    ext.kotlin_version = '1.2.21'

    repositories {
	jcenter()
	mavenCentral()
    }

    dependencies {
	classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.2.21"
}

dependencies {
    classpath "org.jetbrains.kotlin:kotlin-stdlib"
}

sourceSets {
    main.kotlin.srcDirs += "./"
}
a
i
okay, that worked this time
but i now get an error
Copy code
FAILURE: Build failed with an exception.

     Required by:         
         project :
a
you need the 
repositories
outside of 
buildscript
too
so that gradle can resolve the 
kotlin-stdlib
from maven-central
just copy 
repositories
i
it worked
👍 1
does it generate a jar file somewhere in the builds directory?
how do I use the compiled output in any program?
lets say i just want to import from this package in a 
main
function?
a
@Ishan Khare do you use Intellij? Are both projects using gradle?
i
i don't use Intellij, I currently have this project setup using gradle the other one is not using it currently
a
I'd say that its best to use gradle for both projects, then you can let gradle do all of the work for you: https://docs.gradle.org/current/userguide/multi_project_builds.html
i
okay, and how do i distribute this library as a gradle dep?
a
you mean how do you include one gradle project in another?
i
yes
